Q) Write a program that a single user defined thread class to perform the two tasks in parallel

A)

class Mythread extends Thread

{

       public void run()

       {

              if(getName().equals("one"))

              for(int i=1;i<=10;i++)

                     System.out.println(i);

              if(getName().equals("three"))

                     for(int j=11;j<=20;j++)

                           System.out.println(j);

       }

}

classMultiThreadingApplication1 {

       public static void main(String[] args) {

              Mythread t1= new Mythread();

              Mythread t2=new Mythread();

              t1.setName("one");

              t2.setName("three");

              t1.start();

              t2.start();

       }

}

->here getName() is calling by run(). So, it is not calling by using any reference because on which object that runs is calling on that object contain the getName().
